Scope
What we test in Sweetwater County
Concrete testing services
Fresh concrete sampled and tested at the pour — slump, air content, unit weight, and temperature — with cylinders and beams cast on site and broken in the laboratory on the schedule your specification calls for.
ASTM C172ASTM C143ASTM C231ASTM C173ASTM C138ASTM C1064ASTM C31ASTM C39
Aggregate testing services
Gradation, fines content, specific gravity and absorption, unit weight, abrasion resistance, and stockpile moisture for concrete, base course, and backfill aggregates.
ASTM D75ASTM C136ASTM C117ASTM C127ASTM C128ASTM C29ASTM C131ASTM C566
Soil compaction and density testing
Standard and modified Proctor curves in the laboratory and in-place density by nuclear gauge on every lift, so fill, subgrade, and trench backfill are documented against the specified percent compaction.
Soil classification and index testing
Sieve and hydrometer gradation, Atterberg limits, moisture content, specific gravity, and USCS classification for earthwork acceptance, select-fill verification, and geotechnical reports.
ASTM D6913ASTM D7928ASTM D1140ASTM D4318ASTM D2216ASTM D854ASTM D2487
Soil corrosivity testing
pH and electrical resistivity of backfill for MSE walls, pipelines, and buried structures, reported against the specification limits for metallic and geosynthetic reinforcement.
Special inspection (IBC Chapter 17)
ICC-certified special inspectors for reinforced concrete and soils, reporting to the building official alongside the materials test results, so one agency covers both requirements.

Local conditions
Construction materials testing conditions in Sweetwater County
Sweetwater County sits at high desert elevation in southwest Wyoming, where wide daily temperature swings, cold winters, and periodic freeze-thaw cycles create genuine risk for concrete placed without proper monitoring. The region supports active energy sector construction, mine infrastructure, and commercial development—project types where a failed cylinder break or an under-compacted subgrade can trigger costly rework or regulatory delay. Alkali-bearing soils common to the Green River Basin add a corrosivity concern that prudent engineers don't overlook. Our firm dispatches certified field technicians to Sweetwater County from our Salt Lake City regional hub, covering fresh concrete testing, soil compaction, aggregate evaluation, and soil classification under a documented quality system. Every test ties to the applicable ASTM designation, every report is prepared for third-party review. For contractors and engineers working in a remote high-desert environment, that reliability is what the service is built around.
Soils across the Green River Basin and surrounding Sweetwater County terrain are frequently fine-grained or contain soluble salts and sulfates, making soil classification (ASTM D2487) and corrosivity screening relevant on earthwork-intensive projects. Cold overnight temperatures and short shoulder seasons require careful attention to concrete placement temperatures and curing requirements under ACI 306 guidance.
FAQ · Sweetwater County
Given the remote location of many Sweetwater County project sites, how do you coordinate technician dispatch and what lead time should I plan for?
Technicians are dispatched from our Salt Lake City regional hub, approximately 151 miles from Rock Springs. We work on scheduled and project-based coverage. Plan for advance coordination rather than same-day availability. Confirming pour schedules or compaction testing windows at least 24–48 hours ahead allows us to align technician travel with your critical path and avoid unnecessary delays on remote sites.
Wyoming winters hit Sweetwater County hard. What cold-weather concrete testing protocols apply to pours during those conditions?
When concrete is placed in cold conditions, fresh concrete temperature is recorded per ASTM C1064, and cylinder fabrication follows ASTM C31 requirements for initial curing temperature ranges between 60°F and 80°F. Field cylinders must be protected from freezing before transport. ACI 306R provides the cold-weather placing guidance your mix design and curing plan should reference, and our technicians document conditions at the time of each pour.
What soil classification and Proctor testing should I expect on a grading or utility project in Sweetwater County?
Soil classification follows ASTM D2487 (Unified Soil Classification System) using grain-size analysis per ASTM D6913 or D422 and Atterberg limits per ASTM D4318. Standard or modified Proctor compaction curves are established per ASTM D698 or D1557 depending on project specification. Given the variable native soils across the basin, a Proctor run on representative samples before earthwork begins gives your compaction testing a defensible baseline.
How fast can a technician be on site in Sweetwater County?
Sweetwater County work is dispatched through our Salt Lake City, UT regional hub. Scheduled visits are set up by phone at (346) 420-5425; multi-day placements and full-time project assignments are scheduled through a proposal request.
Which office covers materials testing in Sweetwater County, WY?
Field work in Sweetwater County is dispatched through the Salt Lake City, UT regional hub, about 151 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Sweetwater County projects.
Are the technicians you send to Sweetwater County certified?
Yes. Concrete technicians hold ACI Concrete Field Testing Technician Grade I; soils and laboratory technicians hold NICET Construction Materials Testing certifications; special inspection is performed by ICC-certified special inspectors. Where Wyoming agencies or owners require state-specific certifications, those are confirmed in the proposal.
